DCS: what can I say that is accurate and yet fair? (This is harder than it looks.) In one sentence, DCS looks like someone typed notes about a home-brew system and thought it was so good that it could stand on just the notation form of presentation. This PDF lacks a layout, lacks art, and lacks cohesion. If you are good at putting puzzles together, and if you want to give 5x the patience to deciphering the easy yet confusing rule set, then you MIGHT enjoy this game. However, there is not enough "new" or "sizzle" here to warrant the amount of time it would take to fix it. Even at under $2, in my opinion, this is a "miss". Perhaps with a little more TLC and thoughtfulness, DCS could come into its own.
